The bottom of the inside of Fukushima No. 1 nuclear plant’s crippled No. 2 reactor has been revealed in a much clearer and wider range in footage released by plant operator Tokyo Electric Power Co. on April 26.

The film shows the clearest pictures yet inside the containment vessel just below the pressure vessel of the nuclear reactor, which went into meltdown due to the 2011 earthquake and tsunami disaster.

Melted nuclear fuel debris is seen attached to pillars, walls and the ceiling, and accumulations between approximately 40 and 70 centimeters thick are piled up and cover the whole floor.

TEPCO captured the footage on Jan. 19 by attaching a remote-controlled camera to an extendable rod with a span of 16 meters into the containment vessel from an opening in its side.

Excerpts were released at the time, but new processing of the footage has revealed a much clearer picture.

In the bottom of the containment vessel, fuel debris has fused to some areas particularly thickly. It is possible that the bottom of the reactor has several holes that caused the debris to fall and solidify as it cooled.

The improved knowledge of the nuclear reactor’s state will help to calculate an estimate of the amount of the debris inside, and suggest at how it could be removed in the future. TEPCO hopes to start its next investigation inside the reactor within this fiscal year.
